The population covered under this DPR for the ultimate design year and intermediate year will be Lacs and Lacs respectively. However, considering the pumping station and rising main augmentation work going on at present, it is forecasted that more than MLD sewage will reach the STP.

Moreover, the revised and more stringent standards as per GPCB, require removal of nutrients, such as Nitrogen and Phosphorus, for compliance as well. Further, as per development within the project area and as per population forecast, the STP would be receiving more than MLD. Hence, considering design period of 15 years, the augmentation up to MLD is required. However, the available land at Dindoli is about 20 hectares and hence, considering the future sewage generation of MLD, the present land alone would be insufficient.

Hence, part of the Page VII. Construction of Sewage Treatment Plant with Disposal line will be carried out by the qualified contracting agencies by inviting the open tenders. This will result in the protection of the environment of the surrounding area.
